Hello :-)
I have found USB EHCI Controller / HUB on HP EliteBook 2740p to be problematic.
First I was not able to boot the installer from USB memory - it hung
at booloader stage / kernel load randomly.
Now I have problem with Unitek 10/100 Ethernet adapter USB 2.0 - it
seems to crash USB hub, but it works fine on other machines and when I
connect via external USB 2.0 HUB.
Please advise :-)
Tomek
